[Contained list]: Hierarchy list variant 🌳

[dianasanborn]

The problem

This is part of the effort to consolidate the Sustainability Software PAL list guidance with Carbon's contained list guidance.

Figma file: List comparison

Currently there are two very similar components available in both Sustainability PAL and Carbon: the list and contained list. The contained list was contributed from the Carbon for IBM Products side, with some references to the Sustainability PAL list component. Sustainability wasn't involved in the contribution at the time.

There are a lot of similarities to both. Within Sustainability we had a few additional use cases that are used in multiple patterns.

The hierarchy list variant existed in the Sustainability PAL for hierarchical needs in various list scenarios.

Note: This hierarchy list existed before the Carbon tree view so this can be discussed amongst the team whether it's worth having both options or not.

Although the tree view can replace the scenarios where hierarchy lists were used for navigation, it might not work for use cases such as list builders.

The C4IP has a different pattern for hierarchy in the Add and select pattern. There can be some consolidation around here too.

The solution

• Carbon team discuss differences and needs between the Carbon tree view and Hierarchy list variant
• Carbon/C4IP team evaluate hierarchy list variant and add and select hierarchy pattern
• See if there are opportunities to consolidate to support all use cases from the hierarchy list variant. If not, consider including hierarchy variant in the contained list component
